Thanks!
How long did it run on the 2200 mAh cell?

“There’s noticeable tint difference among the four I bought, with two slightly rosy and two slightly green. In my super-scientific bathroom ceiling bounce test, my luxmeter app read about 50% higher than the FC11’s “50LM” setting (using Eneloops) so the OT.50L’s 50 lumen claim is probably accurate, possibly conservative.”
So lemme get this straight, of the four OT.50Ls that ya bought all of them were ‘cool white’, yet with varying tints, green to rosy, correct?
PS. Would ya consider doing a TCR on all four? I’m curious if YOU see any variation in true color rendition between the two tints mentioned. I realize this is subjective to your eyes only.
(TCR definition is in my signature. This can be segregated per individual colors. For instance one emitter may have browns stand out as truer, while another yellows, etc. Just trying to determine how consistent the emitters in the 50.L’s are. Butt I doubt there’s little if any TCR individual/overall color shift on these. Slight tint variations from one 50.L to the next notwithstanding. Kennybobby has pretty much confirmed this and I trust his judgement.)
How appropriately coincidental. One hell of a reptile.
PS. Speakin’ of coincidences, I had a butt knot this morning. Cramp. I know, TMI. :laughing: 
I ran my four samples 7 hours on Eneloops. 4 hours full or near-full brightness. Visible dimming around 5-6 hours. A few lumens or less at 7 hours. Immediately tested the batteries after pulling at the 7 hour mark and got voltages from 0.82V to 1.02V.
Correct. Tint difference isn’t dramatic enough for my phone to capture well, and not enough to be annoying (to me anyway). The left two appear slightly green, right two slightly rosy.
To me the TCR/CRI appears quite poor. Take that with a large grain of salt because of my dislike for super cool temps, and I’m bad at estimating CRI anyway.
A couple other pics. Disassembly is easy enough. A firm counterclock twist and the glued-on top comes off:
And the emitter. The dome isn’t scratched up like it appears, I think those are reflections:
Anyway, obviously not for serious use but definitely worth a dollar just to mess around with.
Nice breakdown, thanks for taking the time. And thanks to OP (and Snakebite) for sharing the find. Snagged 5 today while in the store on unrelated business. Glove box and junk drawer stuffers for a totally painless price. I did throw a Sofirn 18650 in one just out of curiosity. Worked fine, but obviously a little loose around the belt line. 21700 was too long, but fit diameter wise.
Yup, Much thanks for the info!
4 + hrs on eneloops sounds pretty good.
Really not sure what the big deal is.
LOWES has a three pack of all metal lights for $10 they are quite decent and all metal construction. Same 3 x AAA.
You mean the ones with the off center emitter and yellow tinted beams that cost 3x as much? Oh hell yeah, stock up! 
:laughing: 
i get a good 10 hours from a laptop salvage cell
Heh. There's a liniment for that...
Now, a too-common friend of ours locally...Crotalus horridus...did get his name for a reason. I wish snakes fluoresced like scorpions do so you could see them at night with a good UV. Then again, that would probably be even more unsettling than the scorps...it's incredible just how many scorpions can be scuttling around after the sun sets.
At the full up big box WM, not the little neighborhood, they had a huge assortment of lights from several brands, types, etc.
There was the 10-pack of aluminimun tubes AAA, but they are shorter and have a square emitter and reflector, $9.82 with batteries, but i think they will have a yellow stained beamer.
There was a 3 tubes+2 headlights pack with 15 AAA of a much longer and fatter diameter Al tube AAA light with a really long front spring, it might even hold a 20700 cell. i tested one and it has the square emitter and an annoying yellow blob on the edge of the central beam, same price as the 10-pack. Maybe useful as a host for 18650 or bigger, but the beam sux.
A USB rechargeable lithium, 750 lemons with hi and lo modes, $29. Did not test it.
Lots of bling-bling, a feast for your iballs if you don’t mind going offline shopping… 
Gawd, Apple’s taking over everything…
Scorpions. Ah. I can tell ya some kinda horrific painful stories. Suffice to say it’s night now and I don’t wanna keep ya kiddies up and then have the boogie man ta deal with too.
Been stung TWICE the past year. Ya my friend, Mr. Silvestrii. It may be common as house flies butt its sting is A LOT worse than they let on here. Btw, the smaller the pincers the worse the sting - my unfortunate experience.
Ouch…none for me yet but I’ve known several who got zapped. Just let them keep tagging you…eventually you’ll build up immunity. 
Wow watta steal…………
There’s one born every minute…
Note the changes to my signature. The OT 50L is the Reference Standard for determining TCR. If a particular flash demonstrates any TCR flaw then the highest rating it can reach is 9.5. For every TCR flaw the rating is adjusted downward by .5 in the 1-10 scale.
The Dollar Tree light I reviewed four years ago, with a whopping 8 lumens out the front.

i doubt the ot50l is much of a reference standard for anything.
as i noted earlier the color rendering is beat by the ebay 5mm leds.
and i doubt those are the best.
Thanks for shorten it. Much appreciated.
Has been given…
